Kesha Is Back — But Her Legal Struggle Isn't Over

"Rainbow" — Kesha's first album in five years — came out Friday evening to critical acclaim. In one day, the album took the No. 1 spot on the U.S. iTunes albums chart.

Back in July, the artist penned a personal letter describing how her first single from the album was inspired by her depression and obstacles she has overcome.

She wrote: "I dragged myself out of bed and took my emotions to the studio and made art out of them."

"Rainbow" comes in the midst of a bitter legal dispute between Kesha and her producer Lukasz Gottwald, better known as Dr. Luke. In 2014, the singer filed suit after she alleged Gottwald had sexually assaulted her several times. Her request to be released from her contract with Gottwald's record label, Kemosabe Records, was turned down.

Despite the new album, Kesha's legal conflicts aren't over — in fact, Gottwald's defamation and breach-of-contract suit against her is reportedly ramping up again.
